As a process engineer in the resin plant, you are dismayed to find in your morning round that the steam supply to your well stirred resin reactor was lost sometime between 6 and 8 AM. Luckily, the operator shut off the reactor feed and withdrawal streams, but the temperature of the resin in there is now falling as the log sheet shows. (Your capital request to improve reactor insulation got hung up in committee). If the resin in reactor gets down to 40 °C, it will begin to solidify and the cleanup will be a real mess. You decided to do a quick calculation to see how much time you have before this happens. Please present your analysis and calculations in the blank space below. Log Sheet Data Time Resin Temp.
